We found no glaring problems with the reporting of this valid story, so it gets a top 5-star score. But we question whether the subject matter warranted front-page attention in a 2,000-word article. (An earlier comment about a BMJ/BBC report has been deleted. We erroneously connected that report with the subject of this story. They concerned different product types.)

We applaud this story’s attention to an issue than transcends the “study of the day” mentality of most health reporting, but we wish it had attacked the subject with a more careful and evidence-based perspective.
